@Bro-Drillard when I went to HVAC school and had the luxury of having a substitute teacher being a guy who worked on the shit as opposed to a boomer reading out of a book...the guy there lamented the death of cfc and hcfc freon but also said that every few years when (((DuPont))) parents expire they find by pure coincidence that the old freon causes global warming/climate change and force people onto a new one and then make it hard to get the old freon so you're buying a brand new system. Just as intended.
